I may have solved the issue. Using a bluetooth obd2 scanner and Car Scanner app pro. I was able to clear the P0513 code and will wait and see.
It may have been the over pressing of rm411 or during my install trying to figure things out.
I'll post back in a week to let you guys know. thanks for answering Robb.
sidenote: I did replace both OEM keys in early July of this year. During the pandemic I got rid of any outstanding codes and the P0513 was not one of them. I did the programing myself using both (ragged and barely working) OEM keys for them to work. Cost me $40 all in for both keys done. cut them at ace hardware $5 per key and keys were $29.99.
I have owned the car since summer of 2008 and the skreem is original.
I have a video to prove it as well ha ha(new keys never triggered P0513 code), had to look back. So far so good.
I have a feeling it may be firmware for the RM411. Gotta be a known issue, cause the install was military splice, taped, zip tied. Or maybe turning a setting off or reprogramming my new keys once again with the original ones.
